High-Power Multimode Fiber-Coupled Pump Lasers for Demanding Photonics Applications

Yogel’s multimode fiber-coupled pump lasers are engineered as reliable, high-brightness pump sources for modern fiber laser and photonics systems. Designed around industry-standard 105/125 µm multimode fiber with NA = 0.22, these pump modules deliver continuous-wave output powers from 5 W up to 30 W, covering the most widely used pumping wavelengths: 793 nm, 808 nm, 878.6 nm, 915 nm, 940 nm, and 976 nm. By combining precise wavelength control with excellent power stability, they provide a robust building block for OEM integrators and laboratory users who require dependable, repeatable performance over many hours of operation.

In contrast to conventional free-space diode modules, these fiber-coupled pump lasers offer simplified beam delivery and superior alignment stability. The stabilized output is coupled directly into the multimode fiber, enabling easy integration into fiber lasers, fiber amplifiers, and other fiber-based architectures. With wavelength-locked configurations available at key pumping lines such as 976 nm and 808 nm, the modules are optimized for efficient absorption in Yb- and Nd-doped gain media, improving overall system efficiency and reducing thermal load. This makes them an excellent choice for designers upgrading from legacy pump diodes or building new high-brightness laser platforms.

The product line supports both benchtop and compact module formats to match different integration requirements. Benchtop units feature touchscreen operation with local control of power setpoints and real-time monitoring, making them ideal for R&D environments, prototyping, and laboratory testing. For OEM and embedded applications, module versions with RS232 serial communication provide straightforward electronic control and monitoring via a host controller. This flexibility allows the same optical engine to be deployed either as a stand-alone laboratory source or as a deeply integrated subassembly inside a commercial system.

Yogel pays particular attention to power stability and spectral control, two parameters that are critical in precision fiber laser pumping and sensitive biomedical setups. The pump lasers operate in true continuous-wave mode, with short-term power stability on the order of ±0.02 dB (about ±0.5 %) over 15 minutes and long-term stability of ±0.05 dB (about ±1.2 %) over 8 hours. Depending on wavelength, spectral width is narrowed down to sub-nanometer levels for wavelength-locked versions, ensuring efficient and consistent absorption in doped fibers and minimizing gain fluctuations in high-performance fiber laser cavities. This level of stability and spectral purity is comparable to, and in many cases exceeds, typical specifications of similar high-power pump modules used in professional industrial and scientific systems.

The available wavelength and power combinations make these multimode fiber-coupled pumps suitable for a wide span of applications. At 808 nm and 878.6 nm they serve as excellent pump sources for Nd-doped lasers and certain specialty gain media used in solid-state and fiber systems. Around 915 nm and 940 nm, the modules are effective pumps for high-power Yb-doped fiber lasers where broader absorption bands are acceptable or even advantageous for thermal management. At 976 nm, where narrow absorption peaks of Yb-doped fibers are located, the wavelength-locked variants deliver maximum pump efficiency and are widely used in industrial fiber laser pumping, precision materials processing, and high-brightness fiber amplifiers. The 793 nm versions further support specialized fiber lasers and biomedical instrumentation requiring that specific spectral region.

From a system engineering standpoint, these pump modules offer a wide power adjustment range from 10 % to 100 % of rated power, allowing users to finely tune the output level during alignment, characterization, or closed-loop power control. The electrical interface (standard DB9 for RS232) and moderate power consumption simplify integration into existing control electronics. Operating temperature and humidity ranges are chosen to support typical laboratory and light industrial environments, enabling continuous use without stringent environmental conditioning. By combining practical mechanical formats, well-established fiber interfaces, and robust electronic control, Yogel’s multimode fiber-coupled pump lasers are a strong choice for designers who need dependable pump sources for fiber lasers, biomedical instruments, laser material processing tools, and fiber-optic communication or sensor systems.

With customizable output powers, wavelength options, fiber termination, and packaging (benchtop B2/B3 or module M31/M70), these pump lasers can be tailored to fit both new designs and retrofits of existing platforms.

Frequently Asked Questions

What is a multimode fiber coupled pump laser and what are its typical applications?
A multimode fiber coupled pump laser is a high‑power semiconductor laser diode whose output is delivered through a multimode optical fiber, in this case a 105/125 μm fiber with NA=0.22. The Yogel MHPL series operates in continuous‑wave (CW) mode and is designed primarily for pumping fiber lasers and fiber amplifiers, but it is also widely used in biomedical systems, laser material processing, fiber‑optic communication experiments, and general photonics research. Because the light is already fiber‑coupled, integration into fiber‑based systems is straightforward and alignment‑free at the user side.
Which wavelengths and output powers are available for the Yogel MHPL multimode fiber coupled pump lasers?
The MHPL series is offered at several commonly used high‑power pump wavelengths: 793 nm, 808 nm, 878.6 nm, 915 nm, 940 nm, and 976 nm. Typical CW output power options are 5 W, 8 W, 10 W, 12 W, 20 W, 25 W, and 30 W, depending on wavelength and package (benchtop or module). All versions use a 105/125 μm multimode fiber (NA=0.22). Yogel also supports some customization of power level within this range; if a specific combination is not listed, the manufacturer encourages direct contact for custom configurations.
How stable is the output power of the MHPL fiber coupled pump laser over time?
The MHPL series is specified for high power stability, which is critical for stable fiber laser operation. Short‑term stability over 15 minutes is ≤ ±0.02 dB, corresponding to about ±0.5% power variation. Long‑term stability over 8 hours is ≤ ±0.05 dB, roughly ±1.2%. These values are comparable to other premium pump modules listed on FindLight and similar platforms, and ensure reliable performance in continuous‑wave operation for laboratory and industrial use.
What packaging options, control interfaces, and power supplies are available?
The MHPL pump lasers are available either as benchtop units (codes B2/B3) or as compact laser modules (codes M31/M70). Benchtop versions include a touchscreen user interface and RS‑232 serial control via a DB9 female connector, and operate from a universal AC power input of 100–240 V with power consumption under 120 W. Module versions are controlled via RS‑232 through a DB9 female connector and require a DC 12 V supply with up to 60 W consumption, depending on the configured optical output power. This makes them easy to integrate into OEM systems or lab setups with standard serial communication.
What is the wavelength locking and spectral width performance of these pump lasers?
The MHPL family offers wavelength‑locked operation, which means the emission wavelength is stabilized around a target value rather than drifting significantly with temperature or drive current. Typical wavelength accuracy depends on the specific wavelength: for 793/808 nm, ±3 nm; for 976/878.6 nm, as tight as ±0.5 to ±1 nm; and for 915/940 nm, around ±10/±5 nm. The corresponding spectral widths are on the order of 0.5–0.7 nm for the more tightly locked variants and 3–6 nm for broader‑band versions. Such performance is suitable for efficient pumping of Yb‑doped and other rare‑earth‑doped fiber lasers, where coupling to absorption bands is critical.
What fiber type and connector options are supplied, and can I get a collimated output?
Standard MHPL pump lasers use a 105/125 μm multimode fiber with numerical aperture NA=0.22, which is the de‑facto industry standard for high‑power pump delivery and is compatible with many commercial fiber laser pump combiners. The default delivery is via bare fiber, intended for direct fusion splicing or use with user‑supplied connectors or combiners. Yogel also offers an optional fiber collimator, which provides a collimated free‑space beam for applications that require free‑space pumping or easy integration into optical benches.
What are the operating environmental conditions and how is power adjusted?
The specified operating temperature range for the MHPL multimode fiber coupled pump lasers is −5 °C to +35 °C, with humidity from 0% to 70% (non‑condensing typical for similar lasers). Within this range, the output power can be adjusted from 10% to 100% of the rated power, allowing users to tune pump power to match their fiber laser or experimental requirements. Like comparable products on FindLight, it is recommended to ensure adequate thermal management and airflow around the module or benchtop housing to maintain lifetime and stability.
